2 Claims. (Cl. 219-38) My invention relates to fuel feed vaporizing means for internal combustion engines, having reference to an auxiliary vaporizing attachment for installing in the fuel intake of the engine.

In the art to which the invention relates, in starting the engine with a cold mixture, fuel drawn in to the cylinders is insufficiently vaporized and this makes it not only difficult to start the engine but the liquid fuel gets into the cylinders and washes the oil out of the rings and bearings with resulting loss of compression, which is not restored until the motor is well started, during which time the engine runs without oil.

The present invention contemplates provision of a fuel cup or cups for mounting in the intake manifold of the engine and includes a heating element by which fuel trapped in the cups is vaporized and turned into explosive gas.

One of the objects of the invention is accordingly to provide an attachment for the intake manifold of an internal combustion engine providing one or more cups adapted for trapping fuel, and including a heating element for vaporization of the trapped fuel.

A further object of the invention is to provide a vaporizing attachment of the character described for internal combustion engines adaptable for different types of intake manifold, and for mounting in the manifold either as an auxiliary attachment, or incorporated as a permanent part of the manifold construction.

Other features and advantages of the invention will become apparent by reference to the accompanying description taken in conjunction with the drawings wherein like characters of reference indicate like parts throughout the several views and wherein:

Fig. 1 is a side view partly broken away and in section of a double vaporizing unit embodying my improvements and illustrated as complete for installing in an intake manifold providing a double hole.

Figure 2 is a top plan view of the device as illustrated in Figure 1.

Fig. 3 shows a single unit as it would appear mounted in an intake manifold, a fragment of which is shown.

Fig. 4 shows a side view of a form of attachment adapted for mounting in a horizontal type intake.

Fig. 5 shows an end view of a stem with cup of the type illustrated in Figure 4.

Fig. 6 shows a fragmentary side view of a stem with cups of the character shown in Figure 4.

Having reference to the drawings, more particularly to Figures 1, 2 and 3, my vaporizing attachment as therein illustrated is designed to be mounted between the carburetor flange and the intake manifold with gasket at top and bottom, and for which a frame or band I is shown with gaskets at 2 and 3, for mounting between the carburetor flange 4 and manifold intake 5, with the vaporizing attachment depending or projecting within the manifold, it being noted that this is the large part of the intake pipe at the entrance and right under the liquid jets.

The attachment may take a preferred shape as required for each type of manifold, but provides a tube 6 depending from the frame I, which would be by means of an upper bend 1 anchored in the frame, allowing a flow of fuel from the carburetor. Within the tube 6 is an insulated heating element 8 with lead wire 9 from a battery or source of power, the element being grounded to the tube and frame and in turn grounded to the circuit by a combined ground and fuse wire i0, as in Figure 2.

On the lower end of the tube 6 is a fuel trap consisting of a sleeve II for mounting on the tube, said sleeve terminating in a plate 12 with annular upstanding flange i3, and divided by a series offlanges l4 into pockets into which incoming fuel is to be trapped and vaporized by the heat generated from the element 8.

In a type of motor providing a double hole, as in Figures 1 and 2, such as the Ford engine, twin Vaporizers would be provided, each including the essential parts as in Figure 3, and mounted depending in parallel relation within the intake, suspended as previously described for the single heating element.

There is further shown in Figures 4, 5 and 6, a vaporizing attachment in accordance with my invention, substantially as in Figure 3, that is providing the tube 6 supported by a frame I mounted between the carburetor and intake pipe with the tube projecting into the intake. This presupposes a horizontally arranged intake and for this a series of cups 15 are provided at intervals on and around the tube 6, said cups being adapted to trap fuel drawn through the intake from the carburetor.

In the use of the device, fuel injected into the intake from the carburetor may be trapped by the plate l2 or cups I5 and is converted by the heated tube 6 instantly into a vaporized form for drawing into the cylinders. The vaporizer element 8 could include leads to a switch on the vehicle dash board and would be turned on as required, more particularly when starting the motor.

The device is a gas saver because whether turned on or off it agitates the incoming mixture, but without interfering with the flow since it is located in the large part of the intake pipe. It is designed to be used either as an auxiilary attachment installed in an engine as already in use, or to be incorporated as a permanent part of a new engine from the factory.

While I have herein disclosed a preferred embodiment of my invention it is obvious that changes in the construction and arrangement of parts would be permissible and insofar as such changes come within the spirit and scope of the invention as defined in the appended claims they would be considered a part hereof.

Having thus particularly described and ascertained the nature of my invention, what I claim and wish to secure by Letters Patent is:

1. An auxiliary fuel vaporizing attachment for mounting in the intake manifold of an internal combustion engine comprising a tube with means for mounting the tube in the intake manifold at the entrance thereof and projecting axially of the manifold, a heating element for the tube, and a trap on the free end of the tube adapted to 4 intercept fuel in passage through the intake manifold, said trap having a closed bottom portion to contain the fuel trapped therein.

2. An auxiliary fuel vaporizing attachment for mounting in the intake manifold of an internal combustion engine comprising a tube with means for mounting the tube in the intake manifold at the entrance thereof projecting axially of the manifold, a heating element for the tube, and a trap on the free end of the tube adapted to intercept fuel in passage through the manifold and contain the trapped fuel, said trap including a plate fixed transversely to the end of the tube and a peripheral flange on the plate.
